Of the online demos, only the info and the opengl/cl interop demo works, the other ones seem to have a CL_BUILD_PROGRAM_FAILURE error.

On my own code, I also get the CL_BUILD_PROGRAM_FAILURE when I use the CPU device, so there's probably a relation. On some of my newer code, I get JVM stackoverflow crashes that I haven't yet been able to track down (probably related to sloppy coding).

I have switched a while ago from the same AMD cpu with an Nvidia Fermi GPU where everything worked fine with the same "new" code (both AMD CPU and NV GPU OpenCL devices) using an older version of the APP SDK.
